Fig. 2 is the structural schematic diagram of the rotary wheel dehumidifying section 8.
Specific embodiment
Specific embodiment and working principle of the present invention will be described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of low temperature isolator air-conditioning system for the production of medicine enterprise, including Air conditioner box, the air-conditioning It is mixed that just effect fresh air section 1, initial effect filtering section 2, hot pipe section 3, primary heating section 4, the first surface cooling section 5, return air are successively arranged in cabinet Close section 6, medium efficiency filtration section 7, rotary wheel dehumidifying section 8, the second surface cooling section 9, low temperature surface cooling section 10, reheating section 11, humidifier section 12, Fan section 13, high-medium efficient fillter section 14, high-medium efficient wind outlet section 15, medium efficiency filtration section 7, which is arranged, before rotary wheel dehumidifying section 8 can protect Runner extends runner service life;
The first air returning valve 16 is provided between the medium efficiency filtration section 7 and rotary wheel dehumidifying section 8, in the rotary wheel dehumidifying section 8 and second are provided with the second air-valve 17 between surface cooling section 9, bypass section 18 are provided with parallel in the rotary wheel dehumidifying section 8, at this It is provided with third air-valve 19 between bypass section 18 and the medium efficiency filtration section 7, between the bypass section 18 and the second surface cooling section 9 It is provided with the 4th air-valve 20, first air-valve 16, the second air-valve 17, third air-valve 19 and the 4th air-valve 20 are controlled with PLC Device is connected, and the PLC controller controls first air-valve 16, second according to the working condition of the rotary wheel dehumidifying section 8 The opening and closing of air-valve 17, third air-valve 19 and the 4th air-valve 20, specific:
When isolator air-conditioning system, which needs to dehumidify, rotary wheel dehumidifying section 8 is needed to work, PLC controller controls the first air-valve 16 and second air-valve 17 open, third air-valve 19 and the 4th air-valve 20 closing;Isolator air-conditioning is not needed to pharmaceutical production at this time The wind for having certain humidity is provided in live, but to pass through each surface cooling section after the fresh air of isolator air-conditioning and return air mixing, Dehumidification treatments are carried out by rotary wheel dehumidifying section 8 after fresh air and return air mixing, are then sent after subsequent each segment body raw to drug Produce scene;If requiring to room temperature (especially winter), to pass through reheating section 11 by the wind of surface cooling section Certain heating is carried out, the gas come out from low temperature surface cooling section 10 reaches reheating section 11 and heated, that is to say, that runner The wind that dehumidifying section 8 is discharged, which is sent after the second surface cooling section 9, low temperature surface cooling section 10 to reheating section 11, carries out heat exchange, thus Wind in isolator air-conditioning is increased into certain temperature heel row and enters drug production scene.
When isolator air-conditioning system, which does not need dehumidifying, does not need the work of rotary wheel dehumidifying section 8, PLC controller controls third Air-valve 19 and the 4th air-valve 20 are opened, and the first air-valve 16 is closed with third air-valve 17.In the case where weather is particularly suitable, isolation Device air-conditioning does not need to handle the humidity of pharmaceutical production scene air, the operating mode in cooling, at this time fresh air and return It is sent by bypass section 18 to subsequent segment body and is handled after wind mixing, finally sent to pharmaceutical production scene.
In the specific implementation, the different operating mode of purification air-conditioning is controlled and using PLC using PLC come control valve Movement be the prior art, the present embodiment does not do excessive narration, all can be accordingly set inside air-conditioning in each segment body in the prior art There is the basic module of surface air cooler, heater etc, the specific connection type between various components is the well-known technique of the industry, this Example does not do specific description.
From figure 2 it can be seen that the rotary wheel dehumidifying section 8 includes desiccant wheel 8a, upper layer air duct 8b and lower layer air duct 8c, The desiccant wheel 8a is rotatably dispose between upper layer air duct 8b and lower layer air duct 8c, and the upper layer air duct 8b and lower layer air duct Air flow direction between 8c in the upper layer air duct 8b on the contrary, be successively arranged regeneration fresh air area 8d, the first filtering area 8e, the second mistake Area 8f, heating zone 8g, regeneration blower area 8h are filtered, and the heating zone 8g and regeneration blower area 8h are located at the desiccant wheel The two sides of 8a, the settable high-temp resisting high-humidity resisting type filter on the wind pipe of the upper layer air duct 8b.
Preferably, first surface cooling section 5 and the second surface cooling section 9 share same cold source, which is 7/12 DEG C of chilled water, Partial moisture in air is removed by 7/12 DEG C of chilled water in the first surface cooling section 5, realizes water blocking and winter drying;The low temperature The medium to circulate in surface cooling section 10 is low-temperature glycol;The heating zone, reheating section 11 and primary heating section 4 are all made of system One heat source, the heat source are hot steam.
Referring to attached drawing 1, be provided with variable air rate cylinder 21 on the blast pipe of the just effect fresh air section 1, return air mixing section 6 into It is provided on the discharge pipe of air hose and the high-medium efficient wind outlet section 15 and determines air quantity cylinder 22.
By rotary wheel dehumidifying section 8 and relevant each segment body combining form in the present embodiment, room temperature mode, high temperature are realized Mode, low temperature return air mode plurality of operating modes harmony, segment body design rationality is high, not only realize in pharmaceutical production The requirement of low temperature and low humidity, and almost enumerate the low temperature mode of isolator needs, room temperature mode, high temperature mode, disinfection mode Demand, the low temperature refrigerant temperature during rotary wheel dehumidifying is only needed lower than air-supply point, and low temperature temperature-fall period is dry table Cold process no moisture is precipitated, and wholesomeness is also more preferable;Moisture extra in air is directly extracted out with rotary wheel dehumidifying technology, so that after The cold process of continuous cryometer is that dry table is cold to be gone out without elutriation, will not be avoided defrost process in coil pipe frosting, be avoided defrost energy Consumption.
